Finite Element Analysis of the Effect of Blank Holder Force on Deep Drawing of Bottom of Vacuum Flask

Abstract:

Numerical simulation of deep drawing of bottom of vacuum flask is made by means of finite element software ANSYS/LS-DYNA and the potential defect was analyzed. The influence of the blank holder force on deep drawing quality is discussed .The results show that the maximal value of stress and thickness appears in the round corners of die .The maximal increased thickness is sheet flange and the maximal thinning is the round corners of punch. The larger is the blank holder force, the less equal is the thickness and the poorer deep drawing quality.
